摘要：

This study investigates the effects of lanthanum oxide (La2O3) and strontium oxide (SrO) on polyvinyl alcohol (PVA) polymer membranes. The PVA membranes, fabricated using an ultrasound-assisted casting method, include variations with (PVA-SrO), (PVA-La2O3), and a combination of both metal oxides (PVA-SrO-La2O3). X-ray diffraction (XRD) analysis reveals that these membranes exhibit a combination of semi-crystalline and amorphous properties, with the introduction of crystalline peaks due to the addition of SrO and La2O3. Electrical performance assessments, conducted using an I-V source meter and impedance spectroscopy, demonstrate that the metal oxide composite membranes showed improved performance. Mechanical properties were evaluated using Load-Displacement curves, where PVA-SrO-La2O3 exhibited the highest elongation with a value (epsilon) of 134, as measured by Young's modulus, and a resistance value of 12.230 k Omega.
